Theatresports is a form of improvisational theatre, which uses the format of a competition for dramatic effect. Opposing teams can perform scenes based on audience suggestions, with ratings by the audience or by a panel of judges. Developed by director Keith Johnstone in Calgary, Alberta, in 1977, the concept of Theatresports originated in Johnstone's observations of techniques used in professional wrestling to generate heat, or audience reaction.[citation needed]
